Clinical Scorecard: Real-World Assessment of Stapokibart's Effectiveness for Severe Olfactory Dysfunction: Early and Lasting Improvements Regardless of Initial Type 2 Inflammation Levels and Nasal Polyp Severity

At a Glance

CategoryDetail
ConditionChronic rhinosinusitis with nasal polyps (CRSwNP) and olfactory dysfunction (OD)
Key MechanismsInhibition of IL-4 receptor signaling
Target PopulationAdults with moderate-to-severe olfactory dysfunction due to CRSwNP
Care SettingReal-world clinical setting

Key Highlights

  • 40 patients with moderate-to-severe OD received stapokibart 300 mg every 2 weeks for 16 weeks.
  • 52.5% of patients achieved normosmia by Week 16.
  • Significant olfactory improvement observed by Week 2 (P<0.0001).
  • Olfactory recovery consistent across subgroups regardless of baseline inflammatory markers.
  • Higher baseline polyp burden correlated with faster early improvement.

Guideline-Based Recommendations

Diagnosis

  • Endoscopic confirmation of CRSwNP and assessment of olfactory dysfunction.

Management

  • Use of stapokibart for patients inadequately controlled by conventional therapies.

Monitoring & Follow-up

  • Assess olfactory outcomes using smell loss VAS and SSIT-16 at multiple time points.

Risks

  • Consider potential adverse effects of traditional interventions like corticosteroids and surgery.

Patient & Prescribing Data

Adults with endoscopically confirmed CRSwNP and moderate-to-severe OD.

Stapokibart shows rapid and sustained improvement in olfactory function.

Clinical Best Practices

  • Monitor olfactory function and polyp scores during treatment.
  • Consider baseline characteristics when personalizing treatment strategies.
